Automatic benchmarking device of hose filling end-capping machine

Abstract

The invention discloses an automatic benchmarking device of a hose filling end-capping machine. The automatic benchmarking device comprises an annular closed conveying line, a plurality of rotatable hose cup bases, a jacking platform, a pressing ring, a photoelectric sensor and a color mark sensor, wherein the jacking platform is arranged exactly below one hose cup base, and the pressing ring, the photoelectric sensor and the color mark sensor are arranged above the annular closed conveying line and correspond to the jacking platform in position; the bottom of each hose cup base stretches out of the bottom of the annular closed conveying line, and the stretching portion at the bottom of each hose cup base is made of metal materials; a rotating shaft which can rotate is arranged on the top of the jacking platform, and an electromagnet is arranged on the top of the rotating shaft; the pressing ring can ascend, descend and rotate, and an inner cavity of the pressing ring is matched with the tail portion of each hose to be processed through benchmarking; an extendable push rod is further arranged on the portion, on the downstream portion of the pressing ring, of the annular closed conveying line. After the structure is adopted, continuous conveying and benchmarking can be conducted, working efficiency is high, the overall manufacturing cost is low, benchmarking accuracy is high, and the service life of each hose cup base is long.

Description

technical field [0001] The invention relates to a packaging auxiliary device, in particular to an automatic marking device for a hose filling and sealing machine. Background technique [0002] With the improvement of people's material living standards and the rapid development of the modern packaging industry, various daily necessities, cosmetics and medicines packaged in hoses are becoming more and more popular. The demand for packaging has also increased significantly. [0003] In the cosmetics, daily use, medicine, and food industries, there are many products packaged in tubes, such as facial cleanser, toothpaste, ointment, condiments, and so on. There are many process steps. For example, some simple ultrasonic filling and sealing machines in China have multiple processes such as filling, sealing, tail cutting, and tube discharge. Since the hose is mostly in the shape of a cylinder, after the end is sealed, the pipe head becomes a round shape, and the pipe tail is flat,...

AI Technical Summary

Problems solved by technology

[0007] 1. The rotating taper sleeve directly contacts the hose to be marked, and drives the hose to be marked and the floating rotating pipe seat to rotate to perform the marking. The following problems will occur in this process: the hose to be marked, the rotating taper sleeve and the floating The rotating tube base needs to rotate synchronously, so the three should be closely matched. If the fit is too tight, the shape of the hose will be deformed, which will affect the appearance quality of the product. At the same time, the position of the mark will change, and the sensor may make a wrong judgment.

If the fit is too loose, the two will cause the rotation to be out of sync, resulting in inaccurate alignment

In addition, if the hose to be marked is too tightly matched with the rotating drogue, it is not conducive to the disengagement of the rotating drogue or when it is disengaged, it will cause the position of the hose that has been targeted to change.

[0008] 2. The floating and rotating tube base must be able to rotate, but also need to be able to lift up and down, so the structure of the floating and rotating tube base is complicated, and a benchmarking device requires multiple such floating and rotating tube bases, so the overall manufacturing cost is high

In addition, the up and down movement of the floating and rotating tube base will cause wear to the internal bearings, which will deteriorate the rotation synchronization of the floating and rotating tube base, thereby shortening the service life of the floating and rotating tube base

[0009] 3. Due to the limited number of hoses on the rotary worktable, generally around 8-12, if other processes are installed around the rotary worktable, the space will become very crowded

The most important thing is that the working efficiency is low, and the hose needs to be manually placed in or removed from the rotary working table every time

High manual labor intensity, intermittent conveying, low production efficiency

[0014] 3. The use of compression springs and conical hammers can initially position the hose, but the conical hammer cannot rotate with the rotation of the hose. Produces greater rotational resistance and increases the rotational power of the motor
